Abstract

A digital stereo camera (10) using a single sensor array (20) to take both left and right images for stereo (three-dimensional) image capture. In one embodiment, a micro-lens array (16) is used to focus, at a first instant in time, light (""left light"") from a left lens system (12) onto a sensor array (20) for left image capture. Then, the micro-lens array (16) is moved to focus light (""right light"") from a right lens system (14) onto the sensor array (20) for right image capture. In another embodiment, a portion of the left light (the portion having a first polarized direction) and a portion of the right light (the portion having a second polarized direction) are directed to a sensor array (52); the second polarized direction being orthogonal to the first polarized direction. To capture the left image, a polarization filter (56) is used to allow the left light (having the first polarized direction) to pass toward the sensor array (52) while preventing the right light (having the second polarized direction) from reaching the sensor array (52). To capture the right image, polarization direction of the polarization filter (58) is switched to allow only the right light (having the second polarized direction) to reach the sensor array (52).

Description

V. Description of the Invention (1) The Past of the Invention The present invention relates to the art of capturing images. More specifically, the present invention relates to a digital stereo camera that captures a stereoscopic image. Stereo (or 3D (,, 3D ,,)) images include two images that capture the scene. They are left to images and one is a "right image." Images are captured from two different viewpoints. Typically, The two viewpoints are horizontally separated from each other. The horizontal displacement is typically about 65 cm, which is the average distance between the eyes of the viewer. When the left image is viewed by the left eye and the right image is borrowed Viewed by the right eye, a 3D image is presented in the viewer's brain. In this document, "camera," the term refers to a device used to capture still images and moving or recorded images. Different methods have been used to capture stereo images. For example, a non-stereo camera is used to capture a three-dimensional scene by capturing the scene through two consecutive exposures, which are achieved by two different viewpoints. More conveniently, a stereo camera can be used. Stereo cameras usually have two lens systems-one for the left lens system and the other for the right lens system-to capture a 30 image left ~ image is captured by the first film, and the right image is captured by the second film Captured. As far as digital stereo cameras are concerned, two sensor arrays are used. The first sensor array is used to capture the left image and the second sensor array is used to capture the right image. However, using a two-sensor array reduces reliability and increases the cost and weight of a digital stereo camera. Therefore, the need for digital stereo cameras to capture stereo images using only a sensor array arises.

A7 V. Description of the Invention (Elements are assigned the same element number, although similar but changed elements are assigned the same element number but added with a double apostrophe (,,), and different elements are assigned different element numbers. In mosaic In the sensor array 20 ", the sensors marked with", Γ "are red sensors, or sensors that detect the red part of the spectrum;", g "indicates green sensing And "b," which means a blue sensor. At the first instant, the mosaic image sensor array 20 is used, and the first part 20a of the sensor array 20 "is used to capture the left image 1 / 2 resolution, and the second portion 20b "of the sensor array 20, captures 1/2 resolution of the right image. Therefore, at the second instant in time, the first portion 20a of the sensor array 20" "Capture 1/2 resolution of the right image, and the second part 20b of the sensor array 20," capture the 1/2 resolution of the left image. Then, the second set of images (left and right images) is the same as the first Group images (left and right images) are combined to produce two combined images (one (For the left image and the other for the right image), each image has full sensor resolution. Figure 6 shows an alternate embodiment of the device 30 of the present invention, a digital Camera. Referring to Figure 6, the camera 30 includes a left lens system and a right lens system. The left lens system includes an optical element 32 for receiving left light 32L and a left mirror 34 for directing the left light 32L to a polarizing beam splitter. (PBS) 50. The right lens system includes an optical element 42 for receiving the right ray 42R, and mirrors 44 and 46 for directing the right ray 42R to the polarizing beam splitter (PBS) 50. The polarizing beam splitter (PBS) 50 is provided by The reflection guides the left light 34L to a sensor array 52 ′ and passes the sensor by allowing the guided right light 44R to pass through the sensor. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 11 orders (please read first Note on the back, please fill out this page again) 505818 A7 B7 V. Description of the invention (9 array 52 combines left and right light. Polarizing beam splitter (PBS) including polarizing beam splitter film (PBS film) 54 It takes a lot of light to reflect the light in the direction ... (Please read the notes on the back before filling this page), but let the polarized light pass in the second direction (vertical to the first direction). Therefore, only the left A part of the light 34L (which is polarized on the first part) is reflected by the polarizing beam splitter (PBS) 50 toward the sensor array 52, while the rest of the guided left light 34L passes through the polarizing beam splitter (PBS) 50 Similarly, only a portion of the guided right ray 44R (which is polarized on the second portion) passes through a polarizing beam splitter (PBS) 50 toward the sensor array 52, while the remaining portion of the guided right ray 4411 is at the same time Department is not reflected. The combined light rays 56 thus include a portion of the guided left ray 34L having a first polarization direction, and a portion of the guided right ray 4 4 R having a second polarization direction. The combined light 5 6 passes through a polarized light crossing mirror 5 8. In a specific embodiment, the filter 58 is a static filter having a first portion which allows light having only a first polarization direction to pass through, and a second portion is a valley having only a second polarization direction The light passes through. In this embodiment, a part of the 'mirror mirror 58' allows part of the left light ray 34L guided by the combined light 56 to pass because the part of the guided left light ray 34l is polarized in the first direction. Similarly, the second part of the filter 58 allows the guided right ray 44R of the combined ray 56 to pass because the guided right ray 44R is polarized in the second direction. The filter 58 is designed to have alternate first and second parts. Therefore, the corresponding part of the sensor array 52 is 505818 A7 B7. The fifth aspect of the invention (10) captures the left and right images. Static; 5 8 series can be made of sensor array 5 2. In this situation, 'sensors of one half of the light sensor array 5 2 capture light from the left lens system' and sensors of the other half of the light sensor array 52 2 capture light from the right lens system. Alternatively, the polarizing filter 58 may be an active crossing light filter, such as a liquid crystal filter. Therefore, the 'filter 58' can be changed from the first state to the first state. When the light-guiding lens 58 is in the first state, the light-guiding lens 58 can pass all light having a polarized direction, thereby allowing the sensor to capture the image provided by the guided right light 44R. In the second state, the 遽 -light mirror 58 is capable of passing all light having the second polarization direction, thereby allowing the sensor to capture the image provided by the guided left light 34L. The state of the filter 58 can be controlled by applying an electric signal from the control unit 60. The use of these liquid crystal filters to filter polarized light is well known in this art. From the foregoing, it should be apparent that the present invention is novel and provides advantages over current techniques. The invention includes a device for capturing stereoscopic images using only a single sensing array. Although the specific embodiment of the present invention has been described and illustrated above, the present invention is not limited to the specific form or arrangement of elements described and illustrated.
